PROBLEM TO BE SOLVED: To provide a pneumatic tire and a cross-linking rubber composition excellent in abrasion resistance.SOLUTION: A pneumatic tire comprises: bead cores respectively provided for a pair of right/left bead parts; a carcass ply extending from a crown part through both sidewalls to both bead parts and moored by the bead cores; an inner liner disposed at the inner side in the tire radial direction in comparison with the carcass ply; and a tread disposed at the outer side in the tire radial direction in comparison with the carcass ply in which volume of a gap part is 7.5% or less when elongated by applied stress of 3.0 MPa and a component ratio in which weight average molecular weight in the molecular weight distribution measured by the gel permeation chromatography is 1 million or more is 40 mass% or more. A cross-linking rubber composition is given in which volume of a gap part is 7.5% or less when elongated by applied stress of 3.0 MPa, and a component ratio in which weight average molecular weight in the molecular weight distribution measured by the gel permeation chromatography is 1 million or more is 40 mass% or more.SELECTED DRAWING: Figure 2

    【課題】耐摩耗性に優れた空気入りタイヤおよび架橋ゴム組成物を提供すること。【解決手段】左右一対のビード部にそれぞれ設けられたビードコアと、クラウン部から両サイドウォール部を経て両ビード部に延び前記ビードコアに係留されたカーカスプライと、前記カーカスプライよりもタイヤ径方向内側に配置されたインナーライナーと、前記カーカスプライよりもタイヤ径方向外側に設けられ、3.0MPaの印加応力による伸長時の空隙部の体積が7.5%以下であり、ゲル浸透クロマトグラフィにより測定された分子量分布における重量平均分子量が100万以上の成分比率が40質量%以上であるトレッドと、を備えることを特徴とする空気入りタイヤ、および3.0MPaの印加応力による伸長時の空隙部の体積が7.5%以下であり、ゲル浸透クロマトグラフィにより測定された分子量分布における重量平均分子量が100万以上の成分比率が40質量%以上である架橋ゴム組成物。【選択図】図2
